Benefits of technology
The invention is an LED light source that is easy to use and install. It includes a housing with a conical core and a central heat conductor, along with two printed circuit boards connected to the heat conductor. The circuit boards have tension relievers to ensure good electrical contact. A cap is attached to the circuit boards, and a heat sink is attached to the housing. The tension-relieving feature compresses during assembly to ensure good electrical contact. The technical effects of this invention are improved replaceable light sources that are convenient and simple to install.
Problems solved by technology
While working well and being inexpensive, these bulbs have a relatively short life and, of course, the thin filament employed was always subject to breakage due to vibration.
However, these LEDs sources have been hard-wired into their appropriate location, which increase the cost of installation.

Embodiment Construction
[0015]For a better understanding of the present invention, together with other and further objects, advantages and capabilities thereof, reference is made to the following disclosure and appended claims taken in conjunction with the above-described drawings.
[0016]Referring now to the drawings with greater particularity, there is shown in FIG. 1-4 an LED light source 10 comprising a housing 12 having a base 14. A hollow core 16 projects from the base 14, the core 16 being substantially conical. A central heat conductor 17 is centrally located within the hollow core 16 and is substantially solid metal. In a preferred embodiment of the invention the metal is copper.
[0017]A first printed circuit board 18 is connected to one end of the central heat conductor, for example, by screw 19, and a second printed circuit board 20 is fitted to a second, opposite end of the central heat conductor 17. The second printed circuit board 20 has at least one LED 24 operatively fixed thereto and can also...

An LED light source (10) comprises a housing (12) having a base (14) with a hollow core (16) projecting therefrom. The core (16) is substantially conical. A central heat conductor (17) is centrally located within the hollow core (16) and is formed from solid copper. A first printed circuit board (18) is connected to one end of the central heat conductor and a second printed circuit board (20) is fitted to a second, opposite end of the central heat conductor (17). The second printed circuit board (20) has at least one LED (24) operatively fixed thereto. A plurality of electrical conductors (26) has proximal ends (28) contacting electrical traces formed on the second printed circuit board (20) and distal ends (30) contacting electrical traces on the first printed circuit board (18). Each of the electrical conductors (26) has a tension reliever (27) formed therein which axially compresses during assembly. A cap (32) is fitted over the second printed circuit board (20); and a heat sink (34) is attached to the base and in thermal contact with the first printed circuit board.
Description
CROSS-REFERENCE TO RELATED APPLIATIONS[0001]This application claims priority from Provisional Patent Application No. 60 / 507,268 filed Sep. 30, 2003.TECHNICAL FIELD[0002]This application relates to light sources and more particularly to light sources employing light emitting diodes (LED or LEDs). Still more particularly, it relates to light sources useful in the automotive field such as for headlights, taillights, stoplights, fog lights, turn signals, etc.BACKGROUND ART[0003]In the past, most automotive light sources have involved the use of incandescent bulbs. While working well and being inexpensive, these bulbs have a relatively short life and, of course, the thin filament employed was always subject to breakage due to vibration.[0004]Recently some of the uses, particularly the stoplight, have been replaced by LEDs. These solid-state light sources have incredible life times, in the area of 100,000 hours, and are not as subject to vibration failures. However, these LEDs sources hav...
